Complete trigger switch unit. Material used is nylon, almost exactly the same as the SHS nylon switch. This is a 'closed' switch, removing problems you may have with the metal contacts for the fire selector. Standard silver wire with silver motor connectors.

Please note not all basic trigger blocks are compatible with all gearbox shells, some modification made be needed.

This rear/back unit comes with a 12 inch extension wire, makes rear battery jobs far easier.  Sadly these come with tamiya connectors so you'll need to rewire to deans.
